MICROWAVE ABLATION THERAPY FOR THE TREATMENT OF ... Many advantages of microwave ablation over the other ablative therapies in the field of Hepatocellular Carcinoma (HCC) have driven researchers to develop innovative interstitial microwave antennas. A new coaxial double slot antenna for microwave ablation therapy has been proposed in this research paper. A dual-slot microwave antenna for more spherical ablation ... Microwave ablation zones were created by using dual-slot and monopole control antennas for 2, 5, and 10 minutes at 50 and 100 W in ex vivo bovine livers. Dual-slot and monopole antennas were then used to create ablation zones at 100 W for 5 minutes in in vivo porcine livers, which also underwent intraprocedural imaging. FINITE ELEMENT ANALYSIS FOR OPTIMIZING ANTENNA FOR ... antenna with the variations of dimensions of slot from 1 mm to 1.7 mm.
